Agreed mostly, but I beg to differ with your conclusion that this makes the coice of language insignificant.

The point of modern languages (name them functional or not) is to erade whole classes of bugs. Also, it is about making it simple to define good interfaces between components.

So at least your points "focus on quality" and "enhanced architecture" are directly influenced by the programming language. Of course you should train your people to focus on quality, but you also shouldn't make it too hard to get things right in the first place. Of course you should train your people to develop a sense for good architechtures, but you should also provide a formal language that makes it more natural to express their architectural and design decisions.

That way, your training can focus 100% on the real issues, rather than 5% on the real issues and 95% on how to apply them in your programming language, as you need lots of workarounds, wrapper classes and so on. And you don't only have to write them - others also have to read that bunch of mess, and reduce this to the "real point" in their heads. This may be considered a nice mental exercise, but in the end, it's just boring, prone to errors/misunderstandings, and a finally waste of time.
